| Thread-topic: | [PATCH] Fix xm pause/unpause bug |
This small patch intends to fix domain pause/unpause bug. Current xm pause operation will do sync_vcpu_execstate to sync vcpu status, but it saves dom0's fpu and other registers to VTi domain or domainU due to xm pause from control panel. Because sync_vcpu_execstate was called after vcpu_sleep which has saved all necessary status when schedule out ,in addition, currently no lazy states need to be saved in IPF side, so sync_vcpu_execstate needs to do nothing now. Thanks -Xiantao
